Kristin Cavallari: The Hills Was "Pretty Fake," Feud With Lauren Conrad Was Real

Seeing is believing, as the stars of MTV's The Hills know all to well.

During an appearance on Bravo's Watch What Happens Live Dec. 3, former bad girl Kristin Cavallari admitted the reality show was "pretty fake." During her two seasons on the show -- she joined the cast after Lauren Conrad departed midway through season 5 -- Cavallari said she had a series of "fake relationships" and "fake fights."

"But it was fun," the star admitted, "because [when] you're acting, it was more fun for me."

"She is a very pretty girl -- I know she said the same thing. She's very successful," Jay Cutler's fiancee said. "And we actually have had a lot of really fun nights together, so she can be a lot of fun."
